以上のような方法てより、黒色処理鋼板は製造されてい
るが電解着色であるため、生成する黒色皮膜厚が薄く、
また電解条件の若干の逮いや含有成分であるＣＯの分散
状態により色ムラが発生するため、条件設定が離しい。Black-treated steel sheets are produced using the methods described above, but because they are electrolytically colored, the thickness of the black film produced is thin.
In addition, color unevenness occurs due to slight variations in electrolytic conditions and the dispersion state of CO, which is a contained component, so it is difficult to set conditions.
